Although clinically characterized by progressive neurodegeneration, there is also evidence of altered innate immune responses such as neuroinflammation that promote disease progression. We have initiated an investigation into whether phagocytosis, an important innate immune activity and the process by which particles are ingested is defective in NPC. Using an in vitro assay, we have shown that NPC macrophages have a deficiency in the phagocytosis of different particles. We plan to investigate the mechanistic basis for impaired phagocytosis, the contribution that this deficiency makes to disease pathology, and whether therapies that have shown in vivo benefit are able to restore phagocytic activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niemann%20Pick%20Disease%20C" title="Niemann Pick Disease C">Niemann Pick Disease C</a>, <a href="https://publications.waset.org/abstracts/search?q=phagocytosis" title=" phagocytosis"> phagocytosis</a>, <a href="https://publications.waset.org/abstracts/search?q=innate%20immunity" title=" innate immunity"> innate immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=lysosomal%20storage%20disorder" title=" lysosomal storage disorder "> lysosomal storage disorder </a> </p> <a href="https://publications.waset.org/abstracts/34154/innate-immune-dysfunction-in-niemann-pick-disease-type-c" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34154.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5800</span> Garlic Extracts Stimulating Innate Immune System in Marble Goby (Oxyeleotris marmoratus)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiraporn%20Rojtinnakorn">Jiraporn Rojtinnakorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Mallika%20Supa-Aksorn"> Mallika Supa-Aksorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudaporn%20Tongsiri"> Sudaporn Tongsiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Prachaub%20Chaibu"> Prachaub Chaibu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Marble goby is one of high demand consuming in Southeast Asia. However, the product was from riparian fisheries because of low yield in aquaculture, especially in nursery stage. Therefore, we studied for herb supplement in pellet feed of marble goby fingering. Garlic, a common herb and illustrated novel pharmaceutical and medical effectiveness, was considered. Garlic extracts with water (DW), 50% EtOH (50E), 95% EtOH (95E) and diethyl ether (DE) were subjected for feed additive to induce immune response in marble goby fingering for 0 (control), 0.3, 0.5, 1.0, 3.0 and 5.0 % (w/w). After seven days of feeding, blood was collected for analysis of blood composition; i.e. haematocrit (HCT), red blood cells (RBC), white blood cells (WBC) and humoral immune responses; i.e. lysozyme activity (Lys). It was resulted that values of HCT, WBC and Lys in all garlic fed group were significantly different from control (p < 0.05). For HCT, the highest values belonged to 5% DW and 0.5% 95E. For WBC and Lys, the highest values were 5% DW. For RBC, there was not obviously significant (p < 0.05). There were only 3 groups; 0.5% 95E, 1% and 5% DW, showed distinct statistical significance from the other groups. It was concluded that garlic extracts showed satisfy bioactivity to enhancing innate immune response in marble goby fingering. This result will be valuable for specific feed formula of marble goby nursery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=garlic%20extract" title="garlic extract">garlic extract</a>, <a href="https://publications.waset.org/abstracts/search?q=innate%20immune" title=" innate immune"> innate immune</a>, <a href="https://publications.waset.org/abstracts/search?q=marble%20goby" title=" marble goby"> marble goby</a>, <a href="https://publications.waset.org/abstracts/search?q=Oxyeleotris%20marmoratus" title=" Oxyeleotris marmoratus "> Oxyeleotris marmoratus </a> </p> <a href="https://publications.waset.org/abstracts/64906/garlic-extracts-stimulating-innate-immune-system-in-marble-goby-oxyeleotris-marmoratus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64906.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">313</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5799</span> Innate Immunity of Insects in Brief</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Soleymaninejadian">Ehsan Soleymaninejadian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the field of immunology is growing day by day, and its chaotic system amazes more people, greed of research in this area is growing; however dealing with human or mammalian cells such as mice make the research expensive. Although there are some differences between higher animals with insects, importance of innate immunity during evolution made it untouched. So, for understanding the innate immunity insects can be good models. They are cheap; reproduction is fast and in the case genetics, less complicated. In this review, we tried to briefly tackle with important factors in insects’ innate immunity such as melanization, encapsulation, JAK-STAT, IMD, and Toll pathways. At the end, we explained how hormones and nerve system also can impact on immune system and make it more beautiful. In concluding remarks, the possibility of taking help from insect immune system to fight against diseases such as cancer has been considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=insects" title="insects">insects</a>, <a href="https://publications.waset.org/abstracts/search?q=innate%20immunity" title=" innate immunity"> innate immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=melanization" title=" melanization"> melanization</a>, <a href="https://publications.waset.org/abstracts/search?q=intracellular%20pathways" title=" intracellular pathways"> intracellular pathways</a>, <a href="https://publications.waset.org/abstracts/search?q=hormones" title=" hormones"> hormones</a> </p> <a href="https://publications.waset.org/abstracts/74600/innate-immunity-of-insects-in-brief" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74600.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">226</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5798</span> Flocking Swarm of Robots Using Artificial Innate Immune System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muneeb%20Ahmad">Muneeb Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Raza"> Ali Raza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A computational method inspired by the immune system (IS) is presented, leveraging its shared characteristics of robustness, fault tolerance, scalability, and adaptability with swarm intelligence. This method aims to showcase flocking behaviors in a swarm of robots (SR). The innate part of the IS offers a variety of reactive and probabilistic cell functions alongside its self-regulation mechanism which have been translated to enable swarming behaviors. Although, the research is specially focused on flocking behaviors in a variety of simulated environments using e-puck robots in a physics-based simulator (CoppeliaSim); the artificial innate immune system (AIIS) can exhibit other swarm behaviors as well. The effectiveness of the immuno-inspired approach has been established with extensive experimentations, for scalability and adaptability, using standard swarm benchmarks as well as the immunological regulatory functions (i.e., Dendritic Cells’ Maturity and Inflammation). The AIIS-based approach has proved to be a scalable and adaptive solution for emulating the flocking behavior of SR. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20innate%20immune%20system" title="artificial innate immune system">artificial innate immune system</a>, <a href="https://publications.waset.org/abstracts/search?q=flocking%20swarm" title=" flocking swarm"> flocking swarm</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20system" title=" immune system"> immune system</a>, <a href="https://publications.waset.org/abstracts/search?q=swarm%20intelligence" title=" swarm intelligence"> swarm intelligence</a> </p> <a href="https://publications.waset.org/abstracts/168936/flocking-swarm-of-robots-using-artificial-innate-immune-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168936.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5797</span> Hepatocyte-Intrinsic NF-κB Signaling Is Essential to Control a Systemic Viral Infection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sukumar%20Namineni">Sukumar Namineni</a>, <a href="https://publications.waset.org/abstracts/search?q=Tracy%20O%27Connor"> Tracy O'Connor</a>, <a href="https://publications.waset.org/abstracts/search?q=Ulrich%20Kalinke"> Ulrich Kalinke</a>, <a href="https://publications.waset.org/abstracts/search?q=Percy%20Knolle"> Percy Knolle</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathias%20Heikenwaelder"> Mathias Heikenwaelder</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The liver is one of the pivotal organs in vertebrate animals, serving a multitude of functions such as metabolism, detoxification and protein synthesis and including a predominant role in innate immunity. The innate immune mechanisms pertaining to liver in controlling viral infections have largely been attributed to the Kupffer cells, the locally resident macrophages. However, all the cells of liver are equipped with innate immune functions including, in particular, the hepatocytes. Hence, our aim in this study was to elucidate the innate immune contribution of hepatocytes in viral clearance using mice lacking Ikkβ specifically in the hepatocytes, termed IkkβΔᴴᵉᵖ mice. Blockade of Ikkβ activation in IkkβΔᴴᵉᵖ mice affects the downstream signaling of canonical NF-κB signaling by preventing the nuclear translocation of NF-κB, an important step required for the initiation of innate immune responses. Interestingly, infection of IkkβΔᴴᵉᵖ mice with lymphocytic choriomeningitis virus (LCMV) led to strongly increased hepatic viral titers – mainly confined in clusters of infected hepatocytes. This was due to reduced interferon stimulated gene (ISG) expression during the onset of infection and a reduced CD8+ T-cell-mediated response. Decreased ISG production correlated with increased liver LCMV protein and LCMV in isolated hepatocytes from IkkβΔᴴᵉᵖ mice. A similar phenotype was found in LCMV-infected mice lacking interferon signaling in hepatocytes (IFNARΔᴴᵉᵖ) suggesting a link between NFkB and interferon signaling in hepatocytes. We also observed a failure of interferon-mediated inhibition of HBV replication in HepaRG cells treated with NF-kB inhibitors corroborating our initial findings with LCMV infections. Collectively, these results clearly highlight a previously unknown and influential role of hepatocytes in the induction of innate immune responses leading to viral clearance during a systemic viral infection with LCMV-WE. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CD8%2B%20T%20cell%20responses" title="CD8+ T cell responses">CD8+ T cell responses</a>, <a href="https://publications.waset.org/abstracts/search?q=innate%20immune%20mechanisms%20in%20the%20liver" title=" innate immune mechanisms in the liver"> innate immune mechanisms in the liver</a>, <a href="https://publications.waset.org/abstracts/search?q=interferon%20signaling" title=" interferon signaling"> interferon signaling</a>, <a href="https://publications.waset.org/abstracts/search?q=interferon%20stimulated%20genes" title=" interferon stimulated genes"> interferon stimulated genes</a>, <a href="https://publications.waset.org/abstracts/search?q=NF-kB%20signaling" title=" NF-kB signaling"> NF-kB signaling</a>, <a href="https://publications.waset.org/abstracts/search?q=viral%20clearance" title=" viral clearance"> viral clearance</a> </p> <a href="https://publications.waset.org/abstracts/85132/hepatocyte-intrinsic-nf-kb-signaling-is-essential-to-control-a-systemic-viral-infection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85132.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5796</span> Kids and COVID-19: They Are Winning With Their Immunity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Husham%20Bayazed">Husham Bayazed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The infant immune system has a reputation for being weak and underdeveloped when compared to the adult immune system, but the comparison isn’t quite fair. At the start, as the COVID-19 pandemic drags on and evolves, many Pediatricians and kids' parents have been left with renewed questions about the consequences and sequel of infection on children and the steps to be taken if their child, has the symptoms of COVID-19 or tests positive. Recent Findings: Literature reviews and recent studies revealed that children are better than adults at controlling SARS-CoV-2. There was conflicting evidence on age-related differences in ACE2 expression in the nose and lungs. But scientists who measured the ‘viral load’ in children's upper airways have seen no clear difference between children and adults. Moreover, the hypothesis is that kids might be more exposed to other coronaviruses common cold with a production of ready protective antibodies to lock on to the pandemic coronavirus. But the evidence suggests that adults also have this immunity too. Strikingly, these ‘cross-reactive’ antibodies don’t offer any special protection. Summary: One of the few silver linings of the Covid-19 pandemic is that children are relatively spared. The kid's Innate Immunity is hardly the whole story, the innate immune response against SARS-CoV-2 infection is early initiative calm with low immunological tone to prevent an overactive immunity and with rapidly repair damage to the lungs in contrast to stormy waves in adults. Therefore, Kids are at much lower risk of Covid-19 infection and they are still winning the battle against Covid-19 with their innate immunity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kids" title="kids">kids</a>, <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title=" Covid-19"> Covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=immunity" title=" immunity"> immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=ACT2" title=" ACT2"> ACT2</a> </p> <a href="https://publications.waset.org/abstracts/154572/kids-and-covid-19-they-are-winning-with-their-immunity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154572.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5795</span> Enhanced Growth and Innate Immune Response in Scylla serrata Fed Additives Containing Citrus microcarpa and Euphorbia hirta </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaye%20Angelica%20Lacurom">Kaye Angelica Lacurom</a>, <a href="https://publications.waset.org/abstracts/search?q=Keziah%20Macahilo"> Keziah Macahilo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most important and in demand products in the Philippines is Scylla serrata. Despite the increasing demand in the market today, the cost of feeds corresponds to a fraction of 40%-50% of the entire operational of crab production. Raisers and suppliers are seeking alternative ways to lessen their expense with more effective enhancers than the usual feeds. This study aimed to enhance the growth and immune system of the mud crabs using natural antioxidants from plant powders that are available in the locality. There were four treatments: Diet 1: commercially available feeds for the positive control, Diet 2: 1,200 mg/kg Euphorbia hirta , Diet 3: 1,600 mg/kg of Citrus microcarpa, Diet 4: Mixed 1,400 of Euphorbia hirta and Citrus microcarpa. Air-drying was done first-hand followed by the grinding of plants. After which the plants were stored in a container and was added to the feed formulation given. Mud crabs were fed twice a day for 30 days for better results. For inferential analysis, weight gain and survivability were measured, hemolymph was extracted and the Total Hemocycte Count (THC) was determined analyzed. Results showed that the highest THC mean (9.0 x 105 ± 7.1 x 104) and weight gain mean (2.9 x 10± 1.9 x 10) was achieved by Diet 3 with the same survivability rates among other treatments and positive control. While Diet 2 presented the lowest THC mean (7.2 x 105 ±3.5 x 104) and weight gain mean (1.0 x 10± 7.0 x 10-1). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fed%20additives" title="fed additives">fed additives</a>, <a href="https://publications.waset.org/abstracts/search?q=Scylla%20serrata" title=" Scylla serrata"> Scylla serrata</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20growth" title=" enhanced growth"> enhanced growth</a>, <a href="https://publications.waset.org/abstracts/search?q=innate%20immune%20response" title=" innate immune response"> innate immune response</a> </p> <a href="https://publications.waset.org/abstracts/124506/enhanced-growth-and-innate-immune-response-in-scylla-serrata-fed-additives-containing-citrus-microcarpa-and-euphorbia-hirta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124506.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5794</span> ICAM-2, A Protein of Antitumor Immune Response in Mekong Giant Catfish (Pangasianodon gigas)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiraporn%20Rojtinnakorn">Jiraporn Rojtinnakorn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> ICAM-2 (intercellular adhesion molecule 2) or CD102 (Cluster of Differentiation 102) is type I trans-membrane glycoproteins, composing 2-9 immunoglobulin-like C2-type domains.

At the start, as the COVID-19 pandemic drags on and evolves, many Pediatricians and kids' parents have been left with renewed questions about the consequences and sequel of infection on children and the steps to be taken if their child has the symptoms of COVID-19 or tests positive. Recent Findings Literature reviews and recent studies revealed that children are better than adults at controlling SARS-CoV-2. There was conflicting evidence on age-related differences in ACE2 expression in the nose and lungs. But scientists who measured the ‘viral load’ in children's upper airways have seen no clear difference between children and adults. Moreover, the hypothesis is that kids might be more exposed to other coronaviruses common cold, with a production of ready protective antibodies to lock on to the pandemic coronavirus. But the evidence suggests that adults also have this immunity too. Strikingly, these ‘cross-reactive’ antibodies don’t offer any special protection. Summary One of the few silver linings of the Covid-19 pandemic is that children are relatively spared. The kid's Innate Immunity is hardly the whole story, the innate immune response against SARS-CoV-2 infection is early initiative calm with low immunological tone to prevent an overactive immunity and with rapidly repair damage to the lungs in contrast to stormy waves in adults. Therefore, Kids are at much lower risk of Covid-19 infection, and they are still winning the battle against Covid-19 with their innate immunity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title="Covid-19">Covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=kids" title=" kids"> kids</a>, <a href="https://publications.waset.org/abstracts/search?q=ACE2%20receptors" title=" ACE2 receptors"> ACE2 receptors</a>, <a href="https://publications.waset.org/abstracts/search?q=immunity" title=" immunity"> immunity</a> </p> <a href="https://publications.waset.org/abstracts/159020/kids-and-covid-19-they-are-winning-with-their-immunity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159020.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">96</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5792</span> Poly(Amidoamine) Dendrimer-Cisplatin Nanocomplex Mixed with Multifunctional Ovalbumin Coated Iron Oxide Nanoparticles for Immuno-Chemotherapeutics with M1 Polarization of Macrophages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tefera%20Worku%20Mekonnen">Tefera Worku Mekonnen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiseh%20Chih%20Tsai"> Hiseh Chih Tsai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Enhancement of drug efficacy is essential in cancer treatment. The immune stimulator ovalbumin (Ova)-coated citric acid (AC-)-stabilized iron oxide nanoparticles (AC-IO-Ova NPs) and enhanced permeability and retention (EPR) based tumor targeted 4.5 (4.5G) poly(amidoamine) dendrimer-cisplatin nanocomplex (4.5GDP-Cis-pt NC) were used for enhanced anticancer efficiency. The formations of 4.5GDP-Cis-pt NC, AC-IO, and AC-IO-Ova NPs have been examined by FTIR, X-ray diffraction, Raman, and X-ray photoelectron spectroscopy. The conjugation of cisplatin (Cis-pt) with 4.5GDP was confirmed using carbon NMR. The tumor-specific 4.5GDP-Cis-pt NC provided ~45% and 28% cumulative cisplatin release in 72 h at pH 6.5 and 7.4, respectively. A significant immune response with high TNF-α and IL-6 cytokine secretion was confirmed when the co-incubation of AC-IO-Ova with RAW 264.7 or HaCaT cells. AC-IO-Ova NP was biocompatible in different cell lines, even at a high concentration (200 µg mL−1). In contrast, AC-IO-Ova NPs mixed with 4.5GDP-Cis-pt NC (Cis-pt at 15 µg mL−1) significantly increased the cytotoxicity against the cancer cells, which is dose-dependent on the concentration of AC-IO-Ova NPs. The increased anticancer effects may be attributed to the generation of reactive oxygen species (ROS). Moreover, the efficiency of anticancer cells may be further assisted by induction of an innate immune response via M1 macrophage polarization due to the presence of AC-IO-Ova NPs. We provide a better synergestic chemoimmunotherapeutic strategy to enhance the efficiency of anticancer of cisplatin via chemotherapeutic agent 4.5GDP-Cis-pt NC and induction of proinflammatory cytokines to stimulate innate immunity through AC-IO-Ova NPs against tumors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cisplatin-release" title="cisplatin-release">cisplatin-release</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20oxide" title=" iron oxide"> iron oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=ovalbumin" title=" ovalbumin"> ovalbumin</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28amidoamine%29%20dendrimer" title=" poly(amidoamine) dendrimer"> poly(amidoamine) dendrimer</a> </p> <a href="https://publications.waset.org/abstracts/151735/polyamidoamine-dendrimer-cisplatin-nanocomplex-mixed-with-multifunctional-ovalbumin-coated-iron-oxide-nanoparticles-for-immuno-chemotherapeutics-with-m1-polarization-of-macrophages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151735.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5791</span> Evaluation of Immunostimulant Potential of Proteoliposomes Derived from Vibrio anguillarum Administered by Immersion in Zebrafish (Danio rerio)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Caruffo">M.

However, vaccines have been developed based largely on inactivated bacterial formulations, using the whole pathogen. These formulations have demonstrated excellent efficacy against extracellular bacterial pathogens. However diseases with the greatest economic impacts correspond to intracellular bacterial and viral pathogens, vaccines based on these types of agents have shown a discrete effectiveness. It is for these reasons that the development of subunit vaccines based on defined antigens offers a promising solution. The main problem is that subunit vaccines offer a low immunogenicity, since they lack immunostimulatory elements, so that the development of new adjuvants platforms becomes an important challenge for this type of formulations. We evaluate the effect of a formulation based on proteoliposomes of Vibrio anguillarum administered by immersion as a new adjuvant strategy, allowing efficient stimulation of the innate immune system. Proteoliposomes physicochemical properties were evaluated in its ability to produce an inflammatory process. Using zebrafish (Danio rerio) larvae as a model species and the transgenic line (Tg(mpx: GFP)i114) allowed us to track the neutrophil migration in real time. Additionally we evaluated the gene expression of some molecular markers involved in the development of the innate immune response characterizing the adjuvant capacity of the formulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adjuvants" title="adjuvants">adjuvants</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine%20development" title=" vaccine development"> vaccine development</a>, <a href="https://publications.waset.org/abstracts/search?q=zebrafish" title=" zebrafish"> zebrafish</a>, <a href="https://publications.waset.org/abstracts/search?q=innate%20immunity" title=" innate immunity"> innate immunity</a> </p> <a href="https://publications.waset.org/abstracts/33769/evaluation-of-immunostimulant-potential-of-proteoliposomes-derived-from-vibrio-anguillarum-administered-by-immersion-in-zebrafish-danio-rerio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33769.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">556</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5790</span> Mediterranean Diet-Driven Changes in Gut Microbiota Decrease the Infiltration of Inflammatory Myeloid Cells into the Intestinal Tissue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gema%20Go%CC%81mez-Casado">Gema Gómez-Casado</a>, <a href="https://publications.waset.org/abstracts/search?q=Alba%20Rodri%CC%81guez-Mun%CC%83oz"> Alba Rodríguez-Muñoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Virginia%20Mela-Rivas"> Virginia Mela-Rivas</a>, <a href="https://publications.waset.org/abstracts/search?q=Pallavi%20Kompella"> Pallavi Kompella</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Jose%CC%81%20Tinahones-Maduen%CC%83a"> Francisco José Tinahones-Madueña</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Moreno-Indias"> Isabel Moreno-Indias</a>, <a href="https://publications.waset.org/abstracts/search?q=Almudena%20Ortega-Go%CC%81mez"> Almudena Ortega-Gómez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Obesity is a high-priority health problem worldwide due to its high prevalence. The proportion of obese and overweight subjects in industrialized countries exceeds half of the population in most cases. Beyond the metabolic problem, obesity boosts inflammation levels in the organism. The gut microbiota, considered an organ by itself, controls a high variety of processes at a systemic level. In fact, the microbiota interacts closely with the immune system, being crucial in determining the maturation state of neutrophils, key effectors of the innate immune response. It is known that changes in the diet exert strong effects on the variety and activity of the gut microbiota. The effect that those changes have on the axis microbiota-immune response is an unexplored field. In this study, 10 patients with obesity (weight 114,3 ± 14,5Kg, BMI 40,47±3,66) followed a Mediterranean-hypocaloric diet for 3 months, reducing their initial weight by 12,71 ± 3%. A transplant of microbiota from these patients before and after the diet was performed into wild type “germ-free” mice (n=10/group), treated with antibiotics. Six weeks after the transplant, mice were euthanized, and the presence of cells from the innate immune system were analysed in different organs (bone marrow, blood, spleen, visceral adipose tissue, and intestine) by flow cytometry. No differences were observed in the number of myeloid cells in bone marrow, blood, spleen, or visceral adipose tissue of mice transplanted with patient’s microbiota before and after following the Mediterranean diet. However, the intestine of mice that received post-diet microbiota presented a marked decrease in the number of neutrophils (whose presence is associated with tissue inflammation), as well as macrophages. In line with these findings, intestine monocytes from mice with post-diet microbiota showed a less inflammatory profile (lower Ly6Gˡᵒʷ proportion of cells). These results point toward a decrease in the inflammatory state of the intestinal tissue, derived from changes in the gut microbiota, which occurred after a 3-month Mediterranean diet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obesity" title="obesity">obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=Mediterranean%20diet" title=" Mediterranean diet"> Mediterranean diet</a>, <a href="https://publications.waset.org/abstracts/search?q=gut%20microbiota" title=" gut microbiota"> gut microbiota</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20system" title=" immune system"> immune system</a> </p> <a href="https://publications.waset.org/abstracts/157501/mediterranean-diet-driven-changes-in-gut-microbiota-decrease-the-infiltration-of-inflammatory-myeloid-cells-into-the-intestinal-tissue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157501.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5789</span> NK Cells Expansion Model from PBMC Led to a Decrease of CD4+ and an Increase of CD8+ and CD25+CD127- T-Reg Lymphocytes in Patients with Ovarian Neoplasia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Fernandes%20da%20Silva">Rodrigo Fernandes da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Maira%20Cardozo"> Daniela Maira Cardozo</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Cesar%20Martins%20Alves"> Paulo Cesar Martins Alves</a>, <a href="https://publications.waset.org/abstracts/search?q=Sophie%20Fran%C3%A7oise%20Derchain"> Sophie Françoise Derchain</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Guimar%C3%A3es"> Fernando Guimarães</a> </p> <p class="card-text"><strong>Abstract:</strong></p> T-reg lymphocytes are important for the control of peripheral tolerance. They control the adaptive immune system and prevent autoimmunity through its suppressive action on CD4+ and CD8+ lymphocytes. The suppressive action also includes B lymphocytes, dendritic cells, monocytes/macrophages and recently, studies have shown that T-reg are also able to inhibit NK cells, therefore they exert their control of the immune response from innate to adaptive response. Most tumors express self-ligands, therefore it is believed that T-reg cells induce tolerance of the immune system, hindering the development of successful immunotherapies. T-reg cells have been linked to the suppression mechanisms of the immune response against tumors, including ovarian cancer. The goal of this study was to disclose the sub-population of the expanded CD3+ lymphocytes reported by previous studies, using the long-term culture model designed by Carlens et al 2001, to generate effector cell suspensions enriched with cytotoxic CD3-CD56+ NK cells, from PBMC of ovarian neoplasia patients. Methods and Results: Blood was collected from 12 patients with ovarian neoplasia after signed consent: 7 benign (Bng) and 5 malignant (Mlg). Mononuclear cells were separated by Ficoll-Paque gradient. Long-term culture was conducted by a 21 day culturing process with SCGM CellGro medium supplemented with anti-CD3 (10ng/ml, first 5 days), IL-2 (1000UI/ml) and FBS (10%). After 21 days of expansion, there was an increase in the population of CD3+ lymphocytes in the benign and malignant group. Within CD3+ population, there was a significant decrease in the population of CD4+ lymphocytes in the benign (median Bgn D-0=73.68%, D-21=21.05%) (p<0.05) and malignant (median Mlg D-0=64.00%, D-21=11.97%) (p < 0.01) group. Inversely, after 21 days of expansion, there was an increase in the population of CD8+ lymphocytes within the CD3+ population in the benign (median Bgn D-0=16.80%, D-21=38.56%) and malignant (median Mlg D-0=27.12%, D-21=72.58%) group. However, this increase was only significant on the malignant group (p<0.01). Within the CD3+CD4+ population, there was a significant increase (p < 0.05) in the population of T-reg lymphocytes in the benign (median Bgn D-0=9.84%, D-21=39.47%) and malignant (median Mlg D-0=3.56%, D-21=16.18%) group. Statistical analysis inter groups was performed by Kruskal-Wallis test and intra groups by Mann Whitney test. Conclusion: The CD4+ and CD8+ sub-population of CD3+ lymphocytes shifts with the culturing process. This might be due to the process of the immune system to produce a cytotoxic response. At the same time, T-reg lymphocytes increased within the CD4+ population, suggesting a modulation of the immune response towards cells of the immune system. The expansion of the T-reg population can hinder an immune response against cancer. Therefore, an immunotherapy using this expansion procedure should aim to halt the expansion of T-reg or its immunosuppresion capability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=regulatory%20T%20cells" title="regulatory T cells">regulatory T cells</a>, <a href="https://publications.waset.org/abstracts/search?q=CD8%2B%20T%20cells" title=" CD8+ T cells"> CD8+ T cells</a>, <a href="https://publications.waset.org/abstracts/search?q=CD4%2B%20T%20cells" title=" CD4+ T cells"> CD4+ T cells</a>, <a href="https://publications.waset.org/abstracts/search?q=NK%20cell%20expansion" title=" NK cell expansion"> NK cell expansion</a> </p> <a href="https://publications.waset.org/abstracts/17540/nk-cells-expansion-model-from-pbmc-led-to-a-decrease-of-cd4-and-an-increase-of-cd8-and-cd25cd127-t-reg-lymphocytes-in-patients-with-ovarian-neoplasia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17540.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">451</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5788</span> Impact of Tuberculosis Co-infection on Cytokine Expression in HIV-Infected Individuals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Nosik">M.

At the same time, TB infection is associated with clinical progression of HIV-infection. HIV+TB co-infected patients are also at higher risk of acquiring new opportunistic infections. An important feature of disease progression and clinical outcome is the innate and acquired immune responses. HIV and TB, however, have a spectrum of dysfunctions of the immune response. As cytokines play a crucial role in the immunopathology of both infections, it is important to study immune interactions in patients with dual infection HIV+TB. Plasma levels of proinflammatory cytokines IL-2, IFN-γ and immunoregulating cytokines IL-4, IL-10 were evaluated in 75 patients with dual infection HIV+TB, 58 patients with HIV monoinfection and 50 patients with TB monoinfection who were previously naïve for HAART. The decreased levels of IL-2, IFN-γ, IL-4 and IL-10 were observed in patients with dual infection HIV+TB in comparison with patients who had only HIV or TB which means the profound suppression of Th1 and Th2 cytokine secretion. Thus, those cytokines could possibly serve as immunological markers of progression of HIV-infection in patients with TB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HIV" title="HIV">HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis%20%28TB%29" title=" tuberculosis (TB)"> tuberculosis (TB)</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV%20associated%20with%20TB" title=" HIV associated with TB"> HIV associated with TB</a>, <a href="https://publications.waset.org/abstracts/search?q=Th1%2F%20Th2%20cytokine%20expression" title=" Th1/ Th2 cytokine expression"> Th1/ Th2 cytokine expression</a> </p> <a href="https://publications.waset.org/abstracts/42133/impact-of-tuberculosis-co-infection-on-cytokine-expression-in-hiv-infected-individuals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42133.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5787</span> A Galectin from Rock Bream Oplegnathus fasciatus: Molecular Characterization and Immunological Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20S.%20Thulasitha">W.

Galectins are one of the carbohydrate binding lectins that have the ability to identify pathogen by recognition of pathogen associated molecular patterns. Galectins play a vital role in the regulation of innate and adaptive immune responses. Rock bream Oplegnathus fasciatus is one of the most important cultured species in Korea and Japan. Considering the losses due to microbial pathogens, present study was carried out to understand the molecular and functional characteristics of a galectin in normal and pathogenic conditions, which could help to establish an understanding about immunological components of rock bream. Complete cDNA of rock bream galectin like protein B (rbGal like B) was identified from the cDNA library, and the in silico analysis was carried out using bioinformatic tools. Genomic structure was derived from the BAC library by sequencing a specific clone and using Spidey. Full length of rbGal like B (contig14775) cDNA containing 517 nucleotides was identified from the cDNA library which comprised of 435 bp in the open reading frame encoding a deduced protein composed of 145 amino acids. The molecular mass of putative protein was predicted as 16.14 kDa with an isoelectric point of 8.55. A characteristic conserved galactose binding domain was located from 12 to 145 amino acids. Genomic structure of rbGal like B consisted of 4 exons and 3 introns. Moreover, pairwise alignment showed that rock bream rbGal like B shares highest similarity (95.9 %) and identity (91 %) with Takifugu rubripes galectin related protein B like and lowest similarity (55.5 %) and identity (32.4 %) with Homo sapiens. Multiple sequence alignment demonstrated that the galectin related protein B was conserved among vertebrates. A phylogenetic analysis revealed that rbGal like B protein clustered together with other fish homologs in fish clade. It showed closer evolutionary link with Takifugu rubripes. Tissue distribution and expression patterns of rbGal like B upon immune challenges were performed using qRT-PCR assays. Among all tested tissues, level of rbGal like B expression was significantly high in gill tissue followed by kidney, intestine, heart and spleen. Upon immune challenges, it showed an up-regulated pattern of expression with Edwardsiella tarda, rock bream irido virus and poly I:C up to 6 h post injection and up to 24 h with LPS. However, In the presence of Streptococcus iniae rbGal like B showed an up and down pattern of expression with the peak at 6 - 12 h. Results from the present study revealed the phylogenetic position and role of rbGal like B in response to microbial infection in rock bream. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=galectin%20like%20protein%20B" title="galectin like protein B">galectin like protein B</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20response" title=" immune response"> immune response</a>, <a href="https://publications.waset.org/abstracts/search?q=Oplegnathus%20fasciatus" title=" Oplegnathus fasciatus"> Oplegnathus fasciatus</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20characterization" title=" molecular characterization"> molecular characterization</a> </p> <a href="https://publications.waset.org/abstracts/8580/a-galectin-from-rock-bream-oplegnathus-fasciatus-molecular-characterization-and-immunological-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8580.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">354</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5786</span> Cloning and Expression of Human Interleukin 15: A Promising Candidate for Cytokine Immunotherapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadaf%20Ilyas">Sadaf Ilyas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recombinant cytokines have been employed successfully as potential therapeutic agent. Some cytokine therapies are already used as a part of clinical practice, ranging from early exploratory trials to well established therapies that have already received approval. Interleukin 15 is a pleiotropic cytokine having multiple roles in peripheral innate and adaptive immune cell function. It regulates the activation, proliferation and maturation of NK cells, T-cells, monocytes/macrophages and granulocytes, and the interactions between them thus acting as a bridge between innate and adaptive immune responses. Unraveling the biology of IL-15 has revealed some interesting surprises that may point toward some of the first therapeutic applications for this cytokine. In this study, the human interleukin 15 gene was isolated, amplified and ligated to a TA vector which was then transfected to a bacterial host, E. coli Top10F’. The sequence of cloned gene was confirmed and it showed 100% homology with the reported sequence. The confirmed gene was then subcloned in pET Expression system to study the IPTG induced expression of IL-15 gene. Positive expression was obtained for number of clones that showed 15 kd band of IL-15 in SDS-PAGE analysis, indicating the successful strain development that can be studied further to assess the potential therapeutic intervention of this cytokine in relevance to human diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Interleukin%2015" title="Interleukin 15">Interleukin 15</a>, <a href="https://publications.waset.org/abstracts/search?q=pET%20expression%20system" title=" pET expression system"> pET expression system</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20therapy" title=" immune therapy"> immune therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20purification" title=" protein purification"> protein purification</a> </p> <a href="https://publications.waset.org/abstracts/43003/cloning-and-expression-of-human-interleukin-15-a-promising-candidate-for-cytokine-immunotherapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43003.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">413</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5785</span> Do Immune Organ Weights Indicate Immunomodulation of Polyunsaturated Fatty Acids?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Al-Khalifa">H.

A better understanding of molecular changes in microRNAs (miRNAs) and their target genes expression may identify reliable prognostic indicators for cows that will resolve inflammation and resume cyclicity. In the current study, we hypothesized that let-7 miRNAs family has a primary role in the innate immune defence of the endometrium tissue against bacterial infection, which is partly achieved via regulating mRNA stability of pro-inflammatory cytokines at the post-transcriptional level. Therefore, we conducted two experiments. In the first experiment, primary bovine endometrial cells were challenged with clinical (3.0 μg/ml) and sub-clinical (0.5 μg/ml) doses of lipopolysaccharide (LPS) for 24h. In the 2nd experiment, we have investigated the potential role of let-7 miRNAs (let-7a and let-7f) using gain and loss of function approaches. Additionally, tumor necrosis factor alpha (TNFα), transforming growth factor beta 1 induced transcript 1 (TGFB1I1) and serum deprivation response (SDPR) genes were validated using reporter assay. Here we addressed for the first time that let-7 miRNAs have a precise role in bovine endometrium, where LPS dysregulated let-7 miRNAs family expression was associated with an increased pro-inflammatory cytokine level by directly/indirectly targeting the TNFα, interleukin 6 (IL6), nuclear factor kappa-light-chain enhancer of activated B cells (NFκB), TGFβ1I1 and SDPR genes. To our knowledge, this is the first study showing that TNFα, TGFβ1I1 and SDPR were identified and validated as novel let-7 miRNAs targets and could have a distinct role in inflammatory immune response of LPS challenged bovine endometrial cells. Our data represent a new finding by which uterine homeostasis is maintained through functional regulation of let-7a by down-regulation of pro-inflammatory cytokines expression (TNFα and IL6) at the mRNA and protein levels. These findings suggest that LPS serves as a negative regulator of let-7 miRNAs expression and provides a mechanism for the persistent pro-inflammatory phenotype, which is a hallmark of bovine subclinical endometritis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bovine%20endometrial%20cells" title="bovine endometrial cells">bovine endometrial cells</a>, <a href="https://publications.waset.org/abstracts/search?q=let-7" title=" let-7"> let-7</a>, <a href="https://publications.waset.org/abstracts/search?q=lipopolysaccharide" title=" lipopolysaccharide"> lipopolysaccharide</a>, <a href="https://publications.waset.org/abstracts/search?q=pro-inflammatory%20cytokines" title=" pro-inflammatory cytokines"> pro-inflammatory cytokines</a> </p> <a href="https://publications.waset.org/abstracts/38494/let-7-mirnas-regulate-inflammatory-cytokine-production-in-bovine-endometrial-cells-after-lipopolysaccharide-challenge-by-targeting-tnfa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38494.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5783</span> Immune Modulation and Cytomegalovirus Reactivation in Sepsis-Induced Immunosuppression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Lambe">G.

Kapadia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Sepsis is known to cause impairment of both innate and adaptive immunity and involves an early uncontrolled inflammatory response, followed by a protracting immunosuppression phase, which includes decreased expression of cell receptors, T cell anergy and exhaustion, impaired cytokine production, which may cause high risk for secondary infections due to reduced response to antigens. Although human cytomegalovirus (CMV) is widely recognized as a serious viral pathogen in sepsis and immunocompromised patients, the incidence of CMV reactivation in patients with sepsis lacking strong evidence of immunosuppression is not well defined. Therefore, it is important to determine an association between CMV reactivation and sepsis-induced immunosuppression. Aim: To determine the association between incidence of CMV reactivation and immune modulation in sepsis-induced immunosuppression with time. Material and Methods: Ten CMV-seropositive adult patients with severe sepsis were included in this study. Blood samples were collected on Day 0, and further weekly up to 21 days. CMV load was quantified by real-time PCR using plasma. The expression of immunosuppression markers, namely, HLA-DR, PD-1, and regulatory T cells, were determined by flow cytometry using whole blood. Results: At Day 0, no CMV reactivation was observed in 6/10 patients. In these patients, the median length for reactivation was 14 days (range, 7-14 days). The remaining four patients, at Day 0, had a mean viral load of 1802+2599 copies/ml, which increased with time. At Day 21, the mean viral load for all 10 patients was 60949+179700 copies/ml, indicating that viremia increased with the length of stay in the hospital. HLA-DR expression on monocytes significantly increased from Day 0 to Day 7 (p = 0.001), following which no significant change was observed until Day 21, for all patients except 3. In these three patients, HLA-DR expression on monocytes showed a decrease at elevated viral load (>5000 copies/ml), indicating immune suppression. However, the other markers, PD-1 and regulatory T cells, did not show any significant changes. Conclusion: These preliminary findings suggest that CMV reactivation can occur in patients with severe sepsis. In fact, the viral load continued to increase with the length of stay in the hospital. Immune suppression, indicated by decreased expression of HLA-DR alone, was observed in three patients with elevated viral load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CMV%20reactivation" title="CMV reactivation">CMV reactivation</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20suppression" title=" immune suppression"> immune suppression</a>, <a href="https://publications.waset.org/abstracts/search?q=sepsis%20immune%20modulation" title=" sepsis immune modulation"> sepsis immune modulation</a>, <a href="https://publications.waset.org/abstracts/search?q=CMV%20viral%20load" title=" CMV viral load"> CMV viral load</a> </p> <a href="https://publications.waset.org/abstracts/104764/immune-modulation-and-cytomegalovirus-reactivation-in-sepsis-induced-immunosuppression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104764.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5782</span> Ocular Immunology: In Face of Immune Privilege the Eye Remains Vulnerable to Autoimmune and Inflammatory-Mediated Diseases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Husham%20Bayazed">Husham Bayazed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose of Presentation: The eye is one of a few sites in the body with immune privilege (IP). However, this IP is relatively easily bypassed in the face of sufficient strong local or systemic immunological responses. As immune responses are crucial elements of the repair response, the eye has developed distinct mechanisms to deliver immune responses to injury in the avascular regions of the eye. This presentation may cover and provide an overview of the mechanisms that dictate immune cell trafficking to the local ocular microenvironment in response to different autoimmune and inflammatory-mediated diseases. Recent Findings: Literature reviews declare that immune responses and inflammation play a key role in a diverse range of eye diseases. In recent years, our understanding of ocular immune responses has widely spread in ocular surface inflammation, uveitis, age-related macular degeneration (AMD), glaucoma, transplantation rejection, and other ocular diseases. It is becoming increasingly clear that multiple seemingly unrelated diseases involve immune responses with common themes in their ocular pathogenesis. Recent studies are focusing on elucidating the pathogenesis of ocular inflammatory disease to identify new targets for immunotherapy that will not only improve efficacy but also minimize adverse effects from traditional therapy. Summary: While IP was believed to protect the eye from day-to-day inflammatory insults, however, it is relatively easily breached in the face of different strong local or systemic immunological and inflammatory responses. Therefore, the ocular immune response encapsulates the full range of classical and non-classical immune responses and demonstrates many features which are reflected in other tissues, but eye tissues, by modifying these responses, may reveal unexpected and novel findings which are relevant to immune responses generally. This may have therapeutic potential for new targeting immunotherapy, restoring immune tolerance in ocular autoimmune and inflammatory diseases, and preventing rejection such as stem cells, currently being considered for treatment of worldwide blinding diseases such as AMD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ocular%20diseases" title="ocular diseases">ocular diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=immunology" title=" immunology"> immunology</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20privilege" title=" immune privilege"> immune privilege</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotherapy" title=" immunotherapy"> immunotherapy</a> </p> <a href="https://publications.waset.org/abstracts/159133/ocular-immunology-in-face-of-immune-privilege-the-eye-remains-vulnerable-to-autoimmune-and-inflammatory-mediated-diseases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159133.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5781</span> Evaluation of Two DNA Vaccine Constructs in Labeo rohita against Edwardsiella tarda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ranjeeta%20Kumari">Ranjeeta Kumari</a>, <a href="https://publications.waset.org/abstracts/search?q=Makesh%20M"> Makesh M</a>, <a href="https://publications.waset.org/abstracts/search?q=Gayatri%20Tripathi"> Gayatri Tripathi</a>, <a href="https://publications.waset.org/abstracts/search?q=K%20V%20Rajendran"> K V Rajendran</a>, <a href="https://publications.waset.org/abstracts/search?q=Megha%20Bedekar"> Megha Bedekar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A comparative study on DNA immunization with recombinant glyceraldehyde-3-phosphate dehydrogenase (GAPDH) construct of Edwardsiella tarda (pGPD group) and a bicistronic construct expressing GAPDH plus IFN-γ of Labeo rohita as adjuvant (pGPD+IFN group) was undertaken in Labeo rohita along with the control animals.

We aimed to better understand how changing certain material properties can drive immune responses. To this end, we tested immune response to experimental implant coatings that vary in specific characteristics. A layer-by-layer approach was employed to vary surface charge and wettability. Human-based in vitro models (THP-1 macrophages and primary peripheral blood mononuclear cells (PBMCS)) were used to assess immune responses using multiplex cytokine analysis, flow cytometry (CD molecule expression) and microscopy (cell morphology). We observed dramatic differences in immune response due to specific alterations in coating properties. For example altering the surface charge of coating A from anionic to cationic resulted in the substantial elevation of the pro-inflammatory molecules IL-1beta, IL-6, TNF-alpha and MIP-1beta, while the pro-wound healing factor VEGF was significantly down-regulated. We also observed changes in cell surface marker expression in relation to altered coating properties, such as CD16 on NK Cells and HLA-DR on monocytes. We furthermore observed changes in the morphology of THP-1 macrophages following cultivation on different coatings. A correlation between these morphological changes and the cytokine expression profile is ongoing. Targeted changes in biomaterial properties can produce vast differences in immune response. The properties of the coatings examined here may, therefore, be a method to direct specific biological responses in order to improve implant biocompatibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomaterials" title="biomaterials">biomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=coatings" title=" coatings"> coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20system" title=" immune system"> immune system</a>, <a href="https://publications.waset.org/abstracts/search?q=implants" title=" implants"> implants</a> </p> <a href="https://publications.waset.org/abstracts/106219/systematic-analysis-of-immune-response-to-biomaterial-surface-characteristics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106219.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5779</span> Modulation of the Innate Immune Response in Bovine Udder Tissue by Epigenetic Modifiers </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Holm%20Zerbe">Holm Zerbe</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Macias"> Laura Macias</a>, <a href="https://publications.waset.org/abstracts/search?q=Hans-Joachim%20Schuberth"> Hans-Joachim Schuberth</a>, <a href="https://publications.waset.org/abstracts/search?q=Wolfram%20Petzl"> Wolfram Petzl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mastitis is among the most important production diseases in cows. It accounts for large parts of antimicrobial drug use in the dairy industry worldwide. Due to the imminent normative to reduce the use of antimicrobial drugs in livestock, new ways for therapy and prophylaxis of mastitis are needed. Recently epigenetic regulation of inflammation by chromatin modifications has increasingly drawn attention. Currently, some epigenetic modifiers have already been approved for the use in humans, however little is known about their actions in the bovine system. The aim of our study was to investigate whether three selected epigenetic modifiers (Vitamin D3, SAHA and S2101) influence the initial immune response towards mastitis pathogens in bovine udder tissue in vitro. Tissue explants of the teat cistern and udder parenchyma were collected from 21 cows and were incubated for 36 hours in the absence and presence of epigenetic modifiers. Additionally, the tissue was stimulated with heat-inactivated particles of Escherichia coli and Staphylococcus aureus, which are regarded as two of the most important mastitis pathogens. After incubation, the explants were tested by RT-qPCR for transcript abundances of immune-related candidate genes. Gene expression was validated in culture supernatants by an AlphaLISA assay. Furthermore, the culture supernatants were analyzed for their chemotactic capacity through a chemotaxis assay. Statistical analysis of data was performed with the program ‘R’ version 3.2.3. Vitamin D3 had no effect on the immune response of udder tissue in vitro after stimulation with mastitis pathogens. The epigenetic modifiers SAHA and S2101 however significantly blocked the pathogen-induced upregulation of CXCL8, TNFα, S100A9 and LAP (P < 0.05). The regulation of IL10 was not affected by treatment with SAHA and S2101. Transcript abundances for CXCL8 were reflected by IL8 contents and chemotactic activity in culture supernatants. In conclusion, these data show the potential of epigenetic modifiers (SAHA and S2101) to block overshooting inflammation in the udder. Thus epigenetic modifiers may serve in future as immune modulators for the treatment and/or prophylaxis of clinical mastitis.

Among these receptors, the NLRP3 was associated with the recognition of pathogenic fungi in experimental models. NLRP3 operates forming a multiproteic complex called inflammasome, which actives caspase-1, responsible for the production of the inflammatory cytokines IL-1beta and IL-18. In this study, we aimed to investigate the involvement of NLRP3 in the inflammatory response elicited in macrophages against Paracoccidioides brasiliensis (Pb), the etiologic agent of PCM. Macrophages were differentiated from THP-1 cells by treatment with phorbol-myristate-acetate. Following differentiation, macrophages were stimulated by Pb yeast cells for 24 hours, after previous treatment with specific NLRP3 (3,4-methylenedioxy-beta-nitrostyrene) and/or caspase-1 (VX-765) inhibitors, or specific inhibitors of pathways involved in NLRP3 activation such as: Reactive Oxigen Species (ROS) production (N-Acetyl-L-cysteine), K+ efflux (Glibenclamide) or phagossome acidification (Bafilomycin). Quantification of IL-1beta and IL-18 in supernatants was performed by ELISA. Our results showed that the production of IL-1beta and IL-18 by THP-1-derived-macrophages stimulated with Pb yeast cells was dependent on NLRP3 and caspase-1 activation, once the presence of their specific inhibitors diminished the production of these cytokines. Furthermore, we found that the major pathways involved in NLRP3 activation, after Pb recognition, were dependent on ROS production and K+ efflux. In conclusion, our results showed that NLRP3 participates in the recognition of Pb yeast cells by macrophages, leading to the activation of the NLRP3-inflammasome and production of IL-1beta and IL-18. Together, these cytokines can induce an inflammatory response against P. brasiliensis, essential for the establishment of the initial inflammatory response and for the development of the subsequent acquired immune response. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inflammation" title="inflammation">inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-1beta" title=" IL-1beta"> IL-1beta</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-18" title=" IL-18"> IL-18</a>, <a href="https://publications.waset.org/abstracts/search?q=NLRP3" title=" NLRP3"> NLRP3</a>, <a href="https://publications.waset.org/abstracts/search?q=Paracoccidioidomycosis" title=" Paracoccidioidomycosis"> Paracoccidioidomycosis</a> </p> <a href="https://publications.waset.org/abstracts/57374/nlrp3-inflammassome-participates-in-the-inflammatory-response-induced-by-paracoccidioides-brasiliensis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">273</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5776</span> Atherosclerotic Plagues and Immune Microenvironment: From Lipid-Lowering to Anti-inflammatory and Immunomodulatory Drug Approaches in Cardiovascular Diseases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Husham%20Bayazed">Husham Bayazed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A growing number of studies indicate that atherosclerotic coronary artery disease (CAD) has a complex pathogenesis that extends beyond cholesterol intimal infiltration. The atherosclerosis process may involve an immune micro-environmental condition driven by local activation of the adaptive and innate immunity arrays, resulting in the formation of atherosclerotic plaques. Therefore, despite the wide usage of lipid-lowering agents, these devastating coronary diseases are not averted either at primary or secondary prevention levels. Many trials have recently shown an interest in the immune targeting of the inflammatory process of atherosclerotic plaques, with the promised improvement in atherosclerotic cardiovascular disease outcomes. This recently includes the immune-modulatory drug “Canakinumab” as an anti-interleukin-1 beta monoclonal antibody in addition to "Colchicine,” which's established as a broad-effect drug in the management of other inflammatory conditions. Recent trials and studies highlight the importance of inflammation and immune reactions in the pathogenesis of atherosclerosis and plaque formation. This provides an insight to discuss and extend the therapies from old lipid-lowering drugs (statins) to anti-inflammatory drugs (colchicine) and new targeted immune-modulatory therapies like inhibitors of IL-1 beta (canakinumab) currently under investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atherosclerotic%20plagues" title="atherosclerotic plagues">atherosclerotic plagues</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20microenvironment" title=" immune microenvironment"> immune microenvironment</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid-lowering%20agents" title=" lipid-lowering agents"> lipid-lowering agents</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20immunomodulatory%20drugs" title=" and immunomodulatory drugs"> and immunomodulatory drugs</a> </p> <a href="https://publications.waset.org/abstracts/178083/atherosclerotic-plagues-and-immune-microenvironment-from-lipid-lowering-to-anti-inflammatory-and-immunomodulatory-drug-approaches-in-cardiovascular-diseases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178083.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">69</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5775</span> Strategies of Drug Discovery in Insects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaaeddeen%20M.%20Seufi">Alaaeddeen M. Seufi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many have been published on therapeutic derivatives from living organisms including insects. In addition to traditional maggot therapy, more than 900 therapeutic products were isolated from insects. Most people look at insects as enemies and others believe that insects are friends. Many beneficial insects rather than Honey Bees, Silk Worms and Shellac insect could insure human-insect friendship. In addition, insects could be MicroFactories, Biosensors or Bioreactors. InsectFarm is an amazing example of the applied research that transfers insects from laboratory to market by Prof Mircea Ciuhrii and co-workers. They worked for 18 years to derive therapeutics from insects. Their research resulted in production of more than 30 commercial medications derived from insects (e.g. Imunomax, Noblesse, etc.). Two general approaches were followed to discover drugs from living organisms. Some laboratories preferred biochemical approach to purify components of the innate immune system of insects and insect metabolites as well. Then the purified components could be tested for many therapeutic trials. Other researchers preferred molecular approach based on proteomic studies. Components of the innate immune system of insects were then tested for their medical activities. Our Laboratory team preferred to induce insect immune system (using oral, topical and injection routes of administration), then a transcriptomic study was done to discover the induced genes and to identify specific biomarkers that can help in drug discovery. Biomarkers play an important role in medicine and in drug discovery and development as well. Optimum biomarker development and application will require a team approach because of the multifaceted nature of biomarker selection, validation, and application. This team uses several techniques such as pharmacoepidemiology, pharmacogenomics, and functional proteomics; bioanalytical development and validation; modeling and simulation to improve and refine drug development. Our Achievements included the discovery of four components of the innate immune system of Spodoptera littoralis and Musca domestica. These components were designated as SpliDef (defesin), SpliLec (lectin), SpliCec (cecropin) and MdAtt (attacin). SpliDef, SpliLec and MdAtt were confirmed as antimicrobial peptides, while SpliCec was additionally confirmed as anticancer peptide. Our current research is going on to achieve something in antioxidants and anticoagulants from insects. Our perspective is to achieve something in the mass production of prototypes of our products and to reach it to the commercial level. These achievements are the integrated contributions of everybody in our team staff. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AMPs" title="AMPs">AMPs</a>, <a href="https://publications.waset.org/abstracts/search?q=insect" title=" insect"> insect</a>, <a href="https://publications.waset.org/abstracts/search?q=innate%20immunitty" title=" innate immunitty"> innate immunitty</a>, <a href="https://publications.waset.org/abstracts/search?q=therappeutics" title=" therappeutics"> therappeutics</a> </p> <a href="https://publications.waset.org/abstracts/38537/strategies-of-drug-discovery-in-insects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38537.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">370</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5774</span> The Immunology Evolutionary Relationship between Signal Transducer and Activator of Transcription Genes from Three Different Shrimp Species in Response to White Spot Syndrome Virus Infection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20C.%20C.%20Soo">T.

Bhassu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unlike the common presence of both innate and adaptive immunity in vertebrates, crustaceans, in particular, shrimps, have been discovered to possess only innate immunity. This further emphasizes the importance of innate immunity within shrimps in pathogenic resistance. Under the study of pathogenic immune challenge, different shrimp species actually exhibit varying degrees of immune resistance towards the same pathogen. Furthermore, even within the same shrimp species, different batches of challenged shrimps can have different strengths of immune defence. Several important pathways are activated within shrimps during pathogenic infection. One of them is JAK-STAT pathway that is activated during bacterial, viral and fungal infections by which STAT(Signal Transducer and Activator of Transcription) gene is the core element of the pathway. Based on theory of Central Dogma, the genomic information is transmitted in the order of DNA, RNA and protein. This study is focused in uncovering the important evolutionary patterns present within the DNA (non-coding region) and RNA (coding region). The three shrimp species involved are Macrobrachium rosenbergii, Penaeus monodon and Litopenaeus vannamei which all possess commercial significance. The shrimp species were challenged with a famous penaeid shrimp virus called white spot syndrome virus (WSSV) which can cause serious lethality. Tissue samples were collected during time intervals of 0h, 3h, 6h, 12h, 24h, 36h and 48h. The DNA and RNA samples were then extracted using conventional kits from the hepatopancreas tissue samples. PCR technique together with designed STAT gene conserved primers were utilized for identification of the STAT coding sequences using RNA-converted cDNA samples and subsequent characterization using various bioinformatics approaches including Ramachandran plot, ProtParam and SWISS-MODEL. The varying levels of immune STAT gene activation for the three shrimp species during WSSV infection were confirmed using qRT-PCR technique. For one sample, three biological replicates with three technical replicates each were used for qRT-PCR. On the other hand, DNA samples were important for uncovering the structural variations within the genomic region of STAT gene which would greatly assist in understanding the STAT protein functional variations. The partially-overlapping primers technique was used for the genomic region sequencing. The evolutionary inferences and event predictions were then conducted through the Bayesian Inference method using all the acquired coding and non-coding sequences. This was supplemented by the construction of conventional phylogenetic trees using Maximum likelihood method. The results showed that adaptive evolution caused STAT gene sequence mutations between different shrimp species which led to evolutionary divergence event. Subsequently, the divergent sites were correlated to the differing expressions of STAT gene. Ultimately, this study assists in knowing the shrimp species innate immune variability and selection of disease resistant shrimps for breeding purpose. The deeper understanding of STAT gene evolution from the perspective of both purifying and adaptive approaches not only can provide better immunological insight among shrimp species, but also can be used as a good reference for immunological studies in humans or other model organisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gene%20evolution" title="gene evolution">gene evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=JAK-STAT%20pathway" title=" JAK-STAT pathway"> JAK-STAT pathway</a>, <a href="https://publications.waset.org/abstracts/search?q=immunology" title=" immunology"> immunology</a>, <a href="https://publications.waset.org/abstracts/search?q=STAT%20gene" title=" STAT gene"> STAT gene</a> </p> <a href="https://publications.waset.org/abstracts/87267/the-immunology-evolutionary-relationship-between-signal-transducer-and-activator-of-transcription-genes-from-three-different-shrimp-species-in-response-to-white-spot-syndrome-virus-infection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87267.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5773</span> An Analysis of the Impact of Immunosuppression upon the Prevalence and Risk of Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aruha%20Khan">Aruha Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Brynn%20E.%20Kankel"> Brynn E.

Specifically, the long–term or chronic response is associated with the suppression or dysregulation of immune function. It is also widely noted that the occurrence of cancer is greatly correlated to the suppression of the immune system. It is thus necessary to explore the impact of long–term or chronic stress upon the prevalence and risk of cancer. To what extent can the dysregulation of immune function caused by long–term exposure to stress be controlled or minimized? This study focuses explicitly upon immunosuppression due to its ability to increase disease susceptibility, including cancer itself. Based upon an analysis of the literature relating to the fundamental structure of the immune system alongside the prospective linkage of chronic stress and the development of cancer, immunosuppression may not necessarily correlate directly to the acquisition of cancer—although it remains a contributing factor. A cross-sectional analysis of the survey data from the University of Tennessee Medical Center (UTMC) and Harvard Medical School (HMS) will provide additional supporting evidence (or otherwise) for the hypothesis of the study about whether immunosuppression (caused by the chronic stress response) notably impacts the prevalence of cancer. Finally, a multidimensional framework related to education on chronic stress and its effects is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=immune%20system" title="immune system">immune system</a>, <a href="https://publications.waset.org/abstracts/search?q=immunosuppression" title=" immunosuppression"> immunosuppression</a>, <a href="https://publications.waset.org/abstracts/search?q=long%E2%80%93term%20%28chronic%29%20stress" title=" long–term (chronic) stress"> long–term (chronic) stress</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20of%20cancer" title=" risk of cancer"> risk of cancer</a> </p> <a href="https://publications.waset.org/abstracts/118862/an-analysis-of-the-impact-of-immunosuppression-upon-the-prevalence-and-risk-of-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118862.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5772</span> Association of Major Histocompatibility Complex with Cell Mediated Immunity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atefeh%20Esmailnejad">Atefeh Esmailnejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Nikbakht%20Brujeni"> Gholamreza Nikbakht Brujeni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Major histocompatibility complex (MHC) is one of the best characterized genetic regions associated with immune responses and controlling disease resistance in chicken.
